Filed Dec 18, 2019 · Electrical · 122,000 miles · VA

Over the past two years have had to inexplicably jump mdx when it fails to start, usually after sitting over night. (confirmed no auxiliary power left on.) will be fine for a period of time, and symptoms reappear. Have now changed battery twice in past year. Four months after most recent battery change, battery was dead again. This time after jumped the car threw some additional warning lights around charging system. After trying to return to the parking space, the car started was not driving properly, seems to be electrical. After reading forums online my symptoms match very closely to others that have a handsfreelink issue on this model mdx. (parasitic power draw.) contacting acura today, as this time the car is not drive-able.

I've experienced several electrical issues electrical with my vehicle the most troubling was the vehicle completely shut off on the highway then immediately restarted!!!! In addition to this, the next issue is battery performance. The battery is constantly drained. In the 11 years that I owned the vehicle, the battery has been replaced 4 times. (I initially thought this was associated with my bluetooth being connected but I've disconnected this many years ago and the issues still persist. I was strained on winter because the battery drained and was stuck at the airport for 3 1/2 hours waiting for aaa. Lastly, I turned my car on this past sunday when my mil display "check transmission." I brought the car to acura for service and they have informed me that the gear position sensor must be replaced. This is another electrical circuit problem of a mechanical problem with the transmission. Too many electrical issues!!!

Battery kept draining and was dead on a few occasions. I came out to a dead battery on two occassions and then decided to take car to electrical repair shop. Problem was with the bluetooth. This is a widely reported problem with this vehicle. Electrical shop disconnected bluetooth. Honda is aware of this problem yet does nothing about it in form of recall.

Came out to a dead battery after replacing battery just a few months earlier. After already going through the electrical problem of the defective blue tooth, knew it was another electrical problem. Took car to my local shop where he diagnosed another electrical problem, this time with the air conditioner relay/compressor switch. I do not want to be without air conditioning, so had them fix the problem. This is the second electrical problem with the 10 year old mdx with only 90,000 miles. This vehicle has serious electrical problems and they are being ignored by honda motors. I have read many instances online of people who had this same vehicle and the cars have caught on fire from these various electrical problems

The hands free link unit has an issue where it stops working and drains the battery of the car. I've gone through 3 batteries in the last 6 months and when I finally disconnected the hfl unit, the car has been working properly.

This is the third time the electrical system has failed caused by "battery drainage". Local repair shops do not know how to fix problems, but dealer's and honda mechanics are very familiar with this horrible problem. Everyone fixing the problem knows very well this should be "a recall" matter, and creates a great road hazard as well are garage fires and loss of life. The things involved are "blue tooth" modular, air conditioner clutch relay, fuses. Regarding the blue tooth, this modular gets very very hot, and could cause a fire!! When the battery fails to charge while driving to get safely off the highway is very dangerous, much worst at darkness!! Honda needs to get their act together and recall and fix these problems now. My experience happened with the car in motion, and all indicators flashing, rear axle noises, heat inside car, loss of power, and vehicle in "kind of, a limping mode". Very scary and dangerous occurrence. We are the original owner of the car, now with 140,000 miles, and always serviced every 3-5,000 miles. We have taken pride in this vehicle, until this "battery drainage" problem, now is effecting our thoughts about honda motors.

The hands free link (hfl) on this 2007 acura mdx failed to work. The device provides for safe hands free operation of the vehicle and talking on a bluetooth paired phone. In addition it provides for safe operations of various settings of the vehicle w/out having to take your hands off the steering wheel. After researching the problem it seems to be a common problem among honda's and acura's that that the hands free link electronic module malfunctions. In addition the malfunctioning of the hfl causes a battery drain and

Battery in our 2007 acura mdx has had to be replaced 3 times in the past couple of months! Turns out that the handsfree link module was draining the battery and causing it having to be replaced numerous times. This could cause a fire which can pose as a deadly result especially if the car is parked inside of a garage. This needs to be replaced by acura free of charge asap! I disconnected it rather than replacing it after reading the numerous complaints on this matter!

Battery was found to be completely drained on a few occasions after sitting off overnight. After examining possible culprits when the batter was found drained it was found that the handsfree module located in the rear of the center console was hot to the touch. After removing the module completely and recharging the battery this incident of battery drainage has not occurred in 3 months. The handsfree module that operates the bluetooth and handfee functions of the care is defective to the point that it pulls a constant load from the battery even when the car is shut off and keys are not in the ignition. Searching the internet finds many other owners of the same model to have the same problem. This module should be replaced by the manufacturer free of charge because it can lead to a dead battery with no way to start the car, as well as possible fire from the amount of heat built up in the faulty module.
